Project summary

The CarNet project seeks to design and build a self-configuring wireless network suitable for large numbers of smart devices.

Project description

 

Smart devices will require self-configuring wireless data networks that support mobility. Current network technologies are awkward for smart devices: for example, the Internet does not support mobility, the cellular telephone network requires expensive pre-deployed infrastructure, and existing "ad-hoc" networking proposals do not scale well. The CarNet project will design and build a network system that avoids these limitations by use of geographic reasoning.

The scope of the CarNet project includes:

  • scalable distributed location servers, to support mobile hosts and services;
  • location-aware and peer-to-peer applications that take good advantage of Grid's geographic orientation;
  • support for anonymous use, so that location tracking does not compromise users' privacy; iv) integration of the routing system with radio power and spectrum control, to support widely varying node densities; and v) traffic control to spread load over the many independent paths likely to be available in an ad-hoc network.
